The project

Te Ara Tupua is a walking and cycling link to improve transport options between Wellington and Lower Hutt, providing an efficient and attractive choice for commuters. It will deliver a safe, connected and resilient route, enabling more people to walk or bike, and connect with local paths in both Wellington and the Hutt Valley.

Project requirement

The 3.5 kilometre walking and cycling route includes two underpasses below the road to ensure safety for commuters while not interrupting the train line. The key requirements for waterproofing these underpasses were durability for the life of the structure and a leak-free installation to maintain integrity for years to come.

The size and scope of the project meant that strict deadlines were in place and all professions needed to be able to work together to ensure those deadlines were met. The key train line was shut down while works were completed which meant a very tight schedule of works for creating the underpasses.

Allco solution

Allco’s Volclay range was the ideal tanking solution for this project as its durability and effectiveness are second to none. The swellable Voltex actively self-heals and self-seals small concrete cracks caused by ground settlement, concrete shrinkage or seismic action; problems over which there is normally no control.

Keeping the programme on schedule was a credit to all involved thanks to the teamwork and calm approach taken. The challenges suited the Volclay range due to its ability to be applied while other trades were working and to stop and start application quickly when necessary.

“Absolute Waterproofing's application and team work on site ensured a professional and quick installation. Their combined attention to detail and accuracy of application was some of the best I have personally seen in 20 years,” says Alex Valentine, Managing Director, Allco.

Allco was proud to be a part of this project to revolutionise the greater Wellington area and help ensure safe and environmentally friendly routes for commuters and weekend wanderers alike.
